~~ethanol(currently produced mainly from corn, although there's ongoing research into celluosic sources of ethanol(such as sugar cane, sawdust, switchgrass, etc)
~~liquified natural gas(which is used to power municipal vehicles from buses, cars, etc.)
~~biodiesels(made from agricultural products such as soybeans, rapeseed, and even recycled cooking oils)
~~compressed natural gas(several car companies, including Honda, are looking at CNG as a future fuel source)
~~fuel-cell vehicles(using technology currently in used on the shuttle, cars would run on fuel-cells that would produce electricity for a vehicle to run on and produce water as the byproduct)
Any thoughts? Any suggestions? Any opinions?
